I escaped at last!
Enjoyment: Weirdly addictive. Reminds me of Getting Over It.
Concept: It's a good idea for a one-level game!
Presentation: I liked the sounds, especially the bouncy noise. Would be nice to have some indication of which prop the frog will attach to. Maybe have him look at it?
Use of the Limitation: If you're going to do a single, brutally hard level, I like this style better than dying and resetting, because you always have a chance to catch yourself rather than going all the way back to the start.
